Wahi a nā mea hoʻoikaika o ka papa PCB, ua māhele ʻia i nā ʻano aʻe:

1. Phenolic PCB pepa substrate

No ka mea, ua haku ʻia kēia ʻano papa PCB me ka pulp pepa, ka pulp lāʻau, a me nā mea ʻē aʻe, i kekahi manawa e lilo ia i ka pepa pahu, V0 papa, lapalapa-retardant papa a me 94HB, etc. ʻO kāna mea nui he lāʻau pulp fiber pepa, he ʻano PCB. synthesized e ke kaomi resin phenolic.papa.

ʻAʻole pale ahi kēia ʻano substrate pepa, hiki ke kuʻi ʻia, haʻahaʻa ke kumu kūʻai, haʻahaʻa haʻahaʻa, a haʻahaʻa haʻahaʻa pili.ʻIke pinepine mākou i nā substrate pepa phenolic e like me XPC, FR-1, FR-2, FE-3, a me nā mea ʻē aʻe.

2. Papahana PCB hui

Kapa ʻia kēia ʻano papa pauka i ka papa pauka, me ka pepa pulupulu lāʻau a i ʻole ka pulupulu pulp fiber pepa ma ke ʻano he mea hoʻoikaika, a me ka lole aniani i mea hoʻoikaika kino.Hana ʻia nā mea ʻelua i ka resin epoxy pale ahi.Aia ka ʻaoʻao hoʻokahi hapa aniani fiber 22F, CEM-1 a ʻelua ʻaoʻao hapalua aniani fiber papa CEM-3, ma waena o CEM-1 a me CEM-3 ka mea maʻamau i hoʻopaʻa ʻia i nā laminates keleawe.

3. Ke aniani fiber PCB substrate

I kekahi manawa, lilo ia i papa epoxy, papa aniani aniani, FR4, papa fiber, etc. Hoʻohana ia i ka resin epoxy e like me ka lole adhesive a me ka lole aniani i mea hoʻoikaika.He kiʻekiʻe ka wela hana o kēia ʻano papa kaapuni a ʻaʻole pili i ke kaiapuni.Hoʻohana pinepine ʻia kēia ʻano papa i ka PCB ʻaoʻao ʻelua, akā ʻoi aku ke kumukūʻai ma mua o ka substrate PCB composite, a ʻo ka mānoanoa maʻamau ʻo 1.6MM.He kūpono kēia ʻano substrate no nā papa lako mana, nā papa kaapuni kiʻekiʻe, a hoʻohana nui ʻia i nā kamepiula, nā mea pili, a me nā lako kamaʻilio.
